PV Value of Bearings

The max PV value of the CSB-EPB12 series bearing is 0.7N/mm2*m/s which determines the load capacity of bearing is inversely proportional to the speed. Please refer to the chart for more detailed information (Graph EPB12-1).

The Relation of Load, Speed and Temperature

CSB-EPB22 allows the Max static load of 120Mpa, The max compressive deformation rate under the max load is listed in Graph EPB22-2, The actual load capacity of bearing is slightly less than 120Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.0m/s) results into higher temperature (Tmax: 150℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB22-3 for such variation.

The Friction Factor,Wearing and shaft material

Friction Factor
Graph EPB22-4 shows that the friction factor of CSBEPB22 is not considerably affected by the operation speed when the loading is stable. At the meantime, Graph EPB22-5 shows that the friction factor of CSBEPB22 is not considerably affected by the loading when the operation speed is stable. This bearing is the only typical material whose friction factor is not sensitive to the operation speed and loading. Graph EPB22-6 tells that the fiction factor of CSB-EPB22 will not be affected by the shaft roughness when the shaft roughness is better than Ra0.4. The recommended Shaft roughness is Ra0.1~0.4.

Wearing and shaft material

Graph EPB22-7 and Graph EPB22-8 tells that CSBEPB16 is suitable for both hard chrome steel shaft and hardened steel shaft. Graph EPB22-8 shows that the wearing feature of CSB-EPB16 is better in oscillation operation than in rotation operation. Hardened chrome steel shaft and hardened steel shaft is the better choice under oscillation operation and hardened steel shaft and hardened chrome steel shaft is the better choice under rotation operation.

Chemical Resistance

CSB-EPB22 is good at chemical resistance against weak acidic medium and various kinds of lubricants.

Water Absorbability

The water absorb rate of CSB-EPB22 is 1.1% under the atmospheric pressure while it is 4.6% when the material is immerged into water. The application environment has to be considered because of its water absorb properties.

UV Resistance

CSB-EPB22 can become brittle and lost its impact resistance when it is exposed into UV ray for a certain period of time.
